Commissions and bonuses: how they are calculated and negotiated
Commissions and bonuses: how they are calculated and negotiated
A salesperson closed 400 million pesos for the month, the agreed commission was 2% and payroll showed 8 million. Everything looked in order until the accountant presented the rest: contributions, parafiscal charges and accruals on that commission added another 4,666,667, and the month had cost 12,666,667 in real commission. This article shows how a commission is calculated end to end and what to check before signing: the percentage you negotiate with the sales team should be calculated with the payroll settlement open beside it.
Commission, bonus and discretionary bonus: the differences
In daily conversation the three words are used as synonyms; in payroll they produce different effects, and they are defended differently in a labor dispute. A commission is consideration for services: it is agreed before the event occurs, measured with a verifiable indicator and owed if the result happens. A bonus (bonificación) is a recognition the employer grants with no prior obligation to pay it. A bono sits in the middle: the word covers both a discretionary year-end payment and an incentive agreed against objectives.
What decides is the cause of the payment, not its name. If the worker can demand it because an agreed condition was met, it is variable salary, whether it is called commission, bonus, premium or incentive. If it depends on the employer's goodwill, there is no vested right until it accrues, although repeating it for several years creates an expectation that in practice becomes an argument. Social security contributions, parafiscal charges and statutory benefits are calculated on what counts as salary, and not on what does not.
| Figure | What it pays for | Can it be demanded | Contribution base |
|---|---|---|---|
| Commission | A measurable result agreed in advance | Yes, if the condition is met | Yes |
| Objective-based bonus | Written, verifiable targets | Yes, if the target is documented | Yes |
| Occasional bonus | A discretionary recognition | No, until it accrues | Yes, if it becomes habitual |
| Non-statutory allowance | Support that does not pay for work | As agreed | No |
| Expense reimbursement | A cost borne by the worker | Yes, with receipts | No |
When a commission is salary and when it is not
The general rule is simple: a commission is salary. Colombian labor law lists it among the elements that pay for the service, and that classification does not depend on whether it is paid every month or whether the contract presents it as an accessory to the base wage. The cases where a variable payment stays outside are narrow: expense reimbursements, travel allowances under the conditions the law requires, tools and non-statutory allowances that do not pay for work.
Two signals expose a disguised salary: periodicity with a stable calculation logic, and a result-based condition. If it is paid every month with the same formula and the payment depends on what the worker produces, it is remuneration, and whatever the contract calls it loses weight against the fact. Comprehensive salary (salario integral) is a separate case: there the benefit factor is folded into the figure and the variable scheme needs its own review.
How to agree terms: base, rate and accrual point
The base. The word sales is ambiguous. You can pay commission on the invoiced amount, on cash collected, on gross margin, on units shipped or on recovered overdue receivables. Each base rewards a different behavior: invoiced rewards closing, collected rewards collecting, margin rewards selling profitably. It must exclude Colombian VAT, credit notes and unauthorized discounts.
The rate. It can be flat or tiered, and in a tiered scheme it is almost never documented whether the top tier applies to the whole sale or only to the excess. With a quota of 300 million and sales of 400, a 2% rate up to quota plus 3% on the excess gives 6 plus 3: 9 million. If the 3% applied to the full 400, it would give 12. The wording is worth 3 million in a single month.
Accrual. This is the moment the right arises: at shipment, at invoice, at collection or at period close. It is not the same as payment. If the commission accrues with the invoice and is paid on collection, the right already exists and the company carries an obligation it must accrue, even though the cash has not come in.
| Element | What must be in writing | Sample clause |
|---|---|---|
| Base | Calculation universe and exclusions | Invoiced amount excluding Colombian VAT, net of credit notes for the period |
| Rate | Rate and tiers, with application rule | 2% of the base; 3% only on the excess over quota |
| Accrual | Event that makes the commission due | On shipment of the invoiced goods |
| Payment | Date or period | With the payroll of the month following close |
| Reversal | What happens on cancellation or non-payment | Deducted from the next settlement |
| Authorization | Written permission to deduct | The worker authorizes deduction of reversed commissions |
Effect on social security and parafiscal contributions
Contributions are calculated on total earnings, not on the base wage. If the month has 3 million in salary and 8 million in commission, the base is 11. There is no special base for the variable part: it is added and settled the same way. For the exercise in this article the percentages from the example are used: 12.5% health, 16% pension and 9% parafiscal. They are calculation assumptions so the figures can be followed, not a statement of the rates currently in force; check the ones that apply to the year and the activity before using them in a real settlement.
The full rate is split between company and worker: one part is borne by the employer and another is deducted from the salary. The exercise adds the complete rate because it measures the cost of the employment relationship, not just the employer's outlay. The effect is proportional, and that is where the cash risk sits: a month of high sales can leave contributions committed that the company has not yet collected. If the commission is paid before the invoice is collected, the company funds the contribution out of its own cash.
Effect on statutory benefits and final settlement
Severance (cesantías), the annual bonus (prima) and vacation are settled on salary earned, and commission is part of it. Severance and the annual bonus equal one twelfth of the month's earnings. Vacation corresponds to fifteen business days per year of service, handled in the monthly accrual as one twenty-fourth, that is 4.17% of earnings. Interest on severance runs separately, on the accumulated balance, and is not included in the accruals of this exercise.
Final settlement is where disputes appear. When the contract ends, accrued and unpaid commissions must be paid; if the scheme was quarterly and the salesperson leaves in the second month, the proportional share of what accrued is a debt, not a favor. A clause saying that whoever resigns loses the quarter's commission is an advance waiver of rights and rarely holds. If the commission is habitual, the variable average also enters the base for severance indemnities.
The full example: from 400 million in sales to 17.4 million in cost
A salesperson has a base wage of 3,000,000 and a 2% commission on 400,000,000 in sales for the month, that is 8,000,000. Total earnings are 11,000,000. Everything that follows is calculated on that figure, and only on that figure.
| Item | Calculation | Amount |
|---|---|---|
| Base wage | Agreed amount | 3,000,000 |
| Commission | 400,000,000 x 0.02 | 8,000,000 |
| Total earnings | 3,000,000 + 8,000,000 | 11,000,000 |
| Health (12.5% assumed) | 11,000,000 x 0.125 | 1,375,000 |
| Pension (16% assumed) | 11,000,000 x 0.16 | 1,760,000 |
| Parafiscal (9% assumed) | 11,000,000 x 0.09 | 990,000 |
| Severance | 11,000,000 / 12 | 916,667 |
| Annual bonus | 11,000,000 / 12 | 916,667 |
| Vacation | 11,000,000 / 24 | 458,333 |
| Accruals | 916,667 + 916,667 + 458,333 | 2,291,667 |
| Total cost for the month | 11,000,000 + 4,125,000 + 2,291,667 | 17,416,667 |
The total closes at 17,416,667. A month with 11 million in earnings costs 6,416,667 more than the salary and commission together. The surprising figure is the marginal one: the 8 million commission accounts for 12,666,667. Every peso of commission costs about 1.58 pesos, and that 2% of sales is equivalent to 3.17% of invoicing.
Look at that 3.17% against the margin. If gross margin on those sales is 25%, the commission with its load takes almost one eighth. On a product with a 10% margin it takes a third, and the month stops being profitable even though the team met the quota. That calculation is almost never made when the rate is set.
Commissions on receivables and on voided sales
If the commission accrues at invoicing, the company pays for sales it may never collect; if it accrues at collection, the salesperson carries the credit risk and the incentive aligns with cash. Neither is right on its own: it depends on whether you sell for cash, whether the salesperson has influence over collection and how much weight receivables carry. Intermediate mechanisms work if they are written with a deadline: accrue at invoicing with reversal if payment fails, pay part at invoicing and the rest on collection, or pay commission only on collection for credit lines.
Voided sales are the most overlooked point. A credit note issued after payment leaves a commission paid on a sale that never existed. The correction must be agreed: deducted from the next settlement or charged back, and salary deductions require written authorization from the worker and respect the limits set by law. Without it, the employer is left with a receivable that is hard to recover.
Tiered commissions, quotas and accelerators
A well-designed scale has four parts: quota, tiers, accelerator and cap. The quota must be reachable with the team's normal effort; if nobody gets there, the scale discourages and pushes people to hold orders for the following month. Tiered and all-or-nothing plans produce opposite behaviors: under all-or-nothing, a salesperson at 98% gets nothing and has a rational reason not to close; a tiered plan pays each tier reached.
The accelerator is the higher rate applied to the excess over quota, not to the total. It is the most expensive piece when drafted badly: applying it to the total turns a good month into a cost jump nobody budgeted. Before approving it, calculate the marginal cost with the full load, not with the nominal rate. Check fairness too: the same rate on very different territories pays the same effort differently, and that gap turns into turnover.
Monthly, quarterly or deferred payment
Accrual and payment are separate decisions, and confusing them causes almost every cash problem in a variable scheme. Accruing every month and paying quarterly keeps the base stable for contributions and accruals; accruing and paying everything quarterly concentrates earnings in one month and spikes its base. The contribution base has an upper limit measured per period: if three months land in one, part of it may sit above that limit and generate no contribution, while the other two months stay on a low base. Check the limit in force for the year you are settling.
Paying quarterly eases the company's cash and forces the salesperson to finance three months of variable pay; if the base wage does not cover that gap, the scheme drives turnover, and replacing a salesperson with a book of business costs more than the commission saved. The deferred scheme, common in credit sales, pays part at invoicing and the rest on collection: it works if it has a deadline and a verifiable condition; without a deadline the balance stays undefined and becomes a liability that grows quietly.
What happens to commissions when the salesperson leaves
When the contract ends, accrued and unpaid commissions are settled. If the period is half over, you calculate the proportional share of what accrued, not a projection of what the person would have sold; the difference between those two figures feeds claims. Clauses that condition payment on being employed on the settlement date are arguable once the right has accrued: they work for commissions whose triggering event has not occurred, not to erase a vested right.
A final settlement record does not cure a debt if the worker was not paid, and a signed clearance letter does not replace the detail of the calculation. What protects the company is a document with base, period, rate and deductions, signed by both parties. Holding commissions back as security is not a good idea either: the reasonable safeguard is an agreed reversal mechanism, with a deadline and authorization to deduct.
How to control the settlement
Control rests on three reconciliations: what was invoiced against what is commissionable, with an explanation for every difference; credit notes for the period against reversals applied; and receivables against deferred commission still pending collection. One record per period with base, deductions and net, signed by the salesperson and by the reviewer, closes the discussion before it starts.
Separation of duties matters just as much: the person who sells should not calculate their own commission, payroll reviews the base before paying, and accounting accrues on total earnings, not on the base wage. A minimum monthly checklist covers seven points: base reconciled with invoicing, VAT excluded, credit notes applied, written-off receivables identified, accrual and payment documented, contributions and accruals on the total, signed record. If that base is calculated in a spreadsheet running beside the invoicing system, manual reconciliation is where the data gets lost.
Common mistakes
These five mistakes repeat in companies of every size. Each has a visible symptom and a consequence that shows up months later, when the period can no longer be corrected.
| Mistake | Symptom | Consequence | Fix |
|---|---|---|---|
| Paying commission outside the contribution base | Payroll balances on the base wage and commission runs separately | Insufficient contributions, differences and interest in an audit | Add the variable to earnings and resettle |
| Not accruing benefits on commission | The month's expense looks lower than the real cost | Accumulated labor liability surfacing at final settlement | Accrue severance, annual bonus and vacation on the total |
| Paying commission on sales later voided | Credit notes without reversal | Payment on sales that never existed, unrecoverable balance | Reversal clause with deadline and authorization |
| Agreeing terms verbally, with no base or rate | Every settlement is negotiated again | Claims, uneven payments and litigation risk | Written document with base, rate, accrual and payment |
| Paying three months of commission in one | Spike in payroll and contributions | Concentrated base, limit applied once, strained cash | Accrue monthly and pay on the agreed schedule |
All five share the pattern: the scheme is agreed with the sales team and settled by payroll, without the two conversations ever meeting. The mistake is not in the rate; it is the absence of a parallel settlement before approving it.
An honest closing before you decide
This text explains the mechanism; it does not replace the accountant or the labor lawyer. The percentages and amounts in the example are exercise assumptions so the figures can be replicated; the rates, limits and deadlines that apply are those of the year being settled and must be verified. If your company has a collective agreement, a comprehensive salary arrangement or a scheme inherited from another administration, professional review is not optional.
If the team is small and commissions are exceptional, a formal scheme may not be worth it: a short document with base, rate and payment timing is enough. What is never optional is calculating the loaded cost before promising the rate, because a commission is designed with payroll at the table, not only with the sales team. And if the commissionable base is calculated in a file separate from the one that invoices, control is already broken: Kardex Tauro brings inventory, invoicing and accounting into one system, so the figure feeding the commission comes from the same record that creates the sale.
