Structuring ProSal Without Breaking Trust
An identical headline percentage can be two very different offers. This is how to write the formula down so it survives its first slow month.
A ProSal offer breaks down on the same three points every time: how often you reconcile production against the draw, what actually counts as production, and how long a shortfall follows an associate who falls behind it. Leave any of those three unwritten and an identical headline percentage on two offer letters can produce two very different paychecks โ and the trust that breaks over an undocumented formula rarely comes back.
One percentage hides three separate decisions
AVMA data put roughly 56% of associates on ProSal in 2024, which makes it the default compensation model rather than an alternative one.
The structure itself is simple: a guaranteed base functions as a recoverable draw against an agreed percentage of production, and the associate is paid whichever is greater in a given period.
What isn't simple โ and what this page is actually about โ is everything underneath that one sentence.
This page assumes you already know the basic shape of ProSal; if you don't, start with our ProSal and production pay guide, which covers the mechanics candidates are reading before they ever see your offer.
What follows here is the employer's side of the same formula: how to actually decide and write down the three terms that determine whether it reads as fair or as a trap.
None of the three are dictated by law or by a single industry standard.
That's precisely why silence on any of them is a risk โ an associate who can't reconcile their own paycheck will assume the least generous reading of an unwritten term, and in a market where candidates increasingly compare production formulas line by line before signing, that assumption shows up in who takes your offer and who leaves within a year.
Reconciliation cadence: a decision you make, not a norm you follow
How often you settle production against the draw โ monthly, quarterly, or annually โ is one of the specific questions our own candidate-facing contract guidance tells associates to ask before signing.
No published, sourced industry-standard cadence exists to point to here; this is a structuring choice your practice makes and states plainly in the agreement, not a convention you're following.
The trade-off is real either way.
A monthly reconciliation surfaces a shortfall while it's still small, so an associate sees where they stand before a slow stretch compounds into a balance that feels like it arrived all at once.
A quarterly or annual cadence smooths out normal month-to-month swings in caseload โ a slow February doesn't trigger a false alarm โ but it delays the moment an associate actually learns whether they're ahead of or behind their draw, which is exactly the kind of delay that turns a manageable number into a disputed one.
Whichever cadence you choose, generate the same production report every period, in a format the associate can read and check against their own case log.
A number an associate can't verify is a number they'll eventually stop trusting, regardless of whether it was calculated correctly.
Define production before the first paycheck, not after the first dispute
Three definitional gaps are what make two contracts with an identical headline percentage genuinely incomparable, and all three need a plain answer in the document itself.
Production or collections. Production is what the associate generated; collections is what the practice actually received.
Calculating on collections shifts a share of the practice's bad-debt and payment-plan risk onto the associate โ an outcome they don't control.
State which one applies, and if it's collections, say so in the posting or offer rather than letting an associate discover it in their first low-collections month.
Gross or net. A percentage of gross production is a different number from a percentage after deductions.
Name the deduction categories in the agreement itself โ discounts, staff-pet services, write-offs, lab or pharmacy costs โ rather than leaving "net" to mean whatever it means that month.
Attribution. Decide, in writing and before a case comes up, who gets credit when one doctor starts a case another finishes, when a technician performs a dental the associate supervised, or when a case is referred internally.
Silence here doesn't stay silent โ it becomes the argument the first time it matters.
One more split worth stating explicitly if it applies: published industry commentary generally describes product sales as paid at a lower percentage than professional services.
If your formula splits the two, put both percentages in the document โ a single blended rate quoted verbally and a written two-tier rate are not the same offer, even if the headline number sounds identical.
These percentages and splits come from published industry commentary, not from a government survey or statute โ treat them as directional, and have your own compensation structure reviewed by an attorney who works on veterinary employment contracts before finalizing it.
Negative accrual: decide the duration, and what happens at the exit
Negative accrual is what happens when the draw exceeds production: the shortfall becomes a balance owed, typically recovered from future paychecks.
It isn't unreasonable in isolation โ the base was always an advance โ but what determines whether it damages trust is a decision your practice controls: how long that balance is allowed to follow the associate.
Some agreements let a negative balance roll forward indefinitely.
That structure lands hardest on new graduates, whose production is lowest exactly when they're newest, turning a base that was marketed as a guarantee into something closer to a loan.
A growing share of practices instead offer no negative accrual at all โ the base is a genuine floor, and a shortfall is simply absorbed.
Where a practice isn't willing to drop it entirely, the negotiated middle ground is a cap on how much can be recouped, a reset period that clears the balance on a fixed schedule, or conversion of the draw into a true guarantee once production clears an agreed threshold.
Pick one of these and name it; "that's just how ProSal works" is a negotiating position, not a term.
One point our own candidate-facing checklist raises but leaves as an open question for the associate to ask: what happens to an outstanding negative-accrual balance if the associate leaves, or during an approved leave of absence.
No sourced industry norm answers this either way โ which means it's a decision your contract has to make explicitly rather than leave implied.
Whether the balance is waived at separation, remains payable, or pauses accruing during leave should be a sentence in the agreement, not a conversation that happens for the first time during an exit.
Put the whole formula in the offer, not just the base number
A posting or offer letter that states only the base salary and describes the rest as "plus production" is asking a candidate to sign a formula they haven't seen.
If your job description includes a ProSal line, be ready to show the actual reconciliation cadence, the production definition, and the negative-accrual terms as early in the process as the base number itself โ a candidate who has read one associate-contract guide will notice the gap if you don't.
This isn't only a fairness argument.
A transparent, capped formula is also a competitive one: the market is moving toward no-negative-accrual and capped-recoupment terms, and an offer that still relies on an unwritten reconciliation cadence or an unbounded clawback is competing on worse terms than it needs to against practices that have already written theirs down.
This is general information, not legal or financial advice. Compensation terms are negotiated and practice-specific โ have your ProSal structure reviewed by an attorney experienced in veterinary employment contracts before you offer it.
Before you finalize the ProSal formula
- Reconciliation cadence โ monthly, quarterly, or annually โ stated explicitly in the agreement, not left implied.
- Production or collections named plainly, with the exposure that choice creates disclosed up front.
- Gross or net, with every deduction category (discounts, staff-pet services, write-offs, lab/pharmacy costs) listed by name.
- Attribution rules written down for shared, referred, and technician-performed work โ before the first disputed case, not after.
- Whether the professional-services percentage differs from the product-sales percentage, and both rates stated if so.
- Whether negative accrual applies at all, and if so, whether it rolls forward indefinitely, is capped, or resets on a fixed schedule.
- What happens to an outstanding negative-accrual balance at separation or during approved leave.
- A production report format the associate can read and reconcile every period, using the same document each time.
Questions employers ask
How often should we reconcile production against the draw?
There's no published industry-standard cadence to follow โ this is a structuring decision, not a norm. Monthly reconciliation surfaces a shortfall while it's still small; quarterly or annual cadences smooth normal seasonal swings but delay when an associate learns where they stand. Whichever you choose, state it explicitly in the contract and generate the same readable production report every period.
Should ProSal be calculated on production or collections?
Either can work, but they aren't the same offer. Production reflects what the associate generated and keeps bad-debt and payment-plan risk with the practice; collections reflects what the practice actually received and shifts a share of that risk onto the associate. Name which one applies in the written agreement rather than leaving it to be discovered in a low-collections month.
How long should a negative-accrual balance be allowed to roll forward?
Indefinite rollforward is the version associates report as breaking trust, because it lands hardest on new graduates whose production is lowest early on. A growing share of practices now offer no negative accrual at all; where a practice keeps it, a cap on recoupment, a fixed reset period, or conversion to a true guarantee past a production threshold are the commonly negotiated middle grounds โ pick one and write it into the contract.
What happens to a negative-accrual balance if an associate leaves?
No sourced industry norm answers this, which is exactly why it needs to be a stated term rather than an assumption on either side. Decide, and put in writing, whether an outstanding balance is waived at separation, remains payable, or pauses accruing during an approved leave of absence โ and have that language reviewed by an attorney experienced in veterinary employment contracts.
