How to accrue CRO costs without surprising the board

Every clinical stage finance lead has lived through the same board meeting. Burn for the quarter came in well under plan, the board was pleased, and then two months later a CRO invoice for a million dollars of work performed in that quarter arrived and burn for the next quarter looked terrible. Nothing about the trial changed. The accounting simply followed the invoices instead of the work.

The fix is not complicated, but it requires treating clinical accruals as an operational estimate rather than a bookkeeping entry. Here is the method that holds up to auditors and, more importantly, to a board that has been burned before.

Start with a contract map, not the invoices

Every CRO and central lab contract comes with a budget broken into cost categories: study startup, site initiation, per patient costs, monitoring visits, data management, project management, and pass through costs paid to sites and third parties. Build a single workbook per trial that lists every budget line, its total value, its cost driver, and the units the driver is measured in. Per patient costs are driven by enrollment. Site initiation costs are driven by sites activated. Monitoring is driven by visits. Project management is usually straight line over the study duration. Once each line has a driver, the accrual becomes a calculation rather than a guess.

Get the operational data every month

The finance team cannot estimate work performed without knowing how many patients enrolled, how many sites activated, and how many monitoring visits occurred. Clinical operations has this data in the electronic data capture system and in the CRO's monthly status report. Put a recurring thirty minute meeting on the calendar for the third business day of each month where clinical operations walks finance through the numbers. Ask specifically about anything that happened that is not yet on a status report: a site that activated last week, a patient who screened but has not yet been dosed, a change order under negotiation.

The accrual calculation

For each budget line, work performed to date equals units completed multiplied by the unit rate, or percentage of the study period elapsed multiplied by the budget for straight line items. Cumulative accrued expense is the sum of work performed across all lines. The balance sheet accrual, or prepaid where the CRO required an advance, is cumulative work performed minus cumulative invoices received. The monthly expense is the change in cumulative work performed. Book it by trial and by cost category so the P&L tells the same story the contract map does.

Reconcile and true up quarterly

Each quarter, compare your cumulative accrual to the CRO's own budget to actual report and to invoices received. Differences are expected and should be small. Large differences mean either your driver data is stale or the CRO's invoicing is behind, and both are worth a call. Document the true up and the reason for it. Over time the reconciliation history becomes the evidence your auditor asks for, and it lets you show the board a trend of accrual accuracy rather than asking them to trust you.

Change orders and scope creep

Protocol amendments, additional sites, extended enrollment windows, and added assessments all generate change orders that can add twenty to forty percent to a study budget over its life. A change order that has been verbally agreed but not signed is still work that is being performed. Track change orders in the contract map from the moment they are proposed, with a status column, and accrue for the work once it starts regardless of signature. The board should hear about a material change order the month it is proposed, with the effect on the trial budget and on runway, not when the amended invoice arrives.

What the board should see

• Clinical spend by trial, actual versus budget, with the accrual clearly separated from cash paid.
• A one line explanation of any variance over ten percent, in operational terms: enrollment ahead of plan, a site activation delayed, a change order signed.
• The cumulative trial cost to date against the total contracted budget, so they can see how much of the study is behind you.
• Runway with the clinical forecast baked in, updated for every change in enrollment timing.

A board that gets these four things every quarter stops asking whether the clinical numbers are right. That is worth more than any single accrual being exactly correct.
