Per-Return Fee or Seasonal Capacity Block? Choosing the Right Pricing Model

The first practical question most firms ask isn't about turnaround or review — it's how the engagement gets priced. Two models come up: pay per return as they're sent, or reserve a block of capacity for the season upfront. Both work. They just optimize for different things.

What per-return pricing optimizes for

Per-return pricing means your firm pays only for what it sends — no return, no charge. That makes it the lower-risk starting point for a first season, or for a firm whose overflow volume swings hard from year to year. There's no forecast to get wrong; the cost tracks the workload exactly.

The tradeoff is that per-return pricing doesn't reserve anything. During the sharpest weeks of the season, when every firm's overflow volume peaks at once, a standing capacity block gets priority ahead of return-by-return requests.

What a capacity block optimizes for

A seasonal capacity block reserves a set volume of prep hours or returns in advance, usually at a lower effective per-return cost than paying one at a time. It also reserves priority — returns sent against that block move through the queue ahead of ad hoc requests during the busiest weeks.

The tradeoff runs the other way: a capacity block is a commitment made before the season shows its hand. A firm that overestimates its overflow volume pays for capacity it didn't use; a firm that underestimates it is back to per-return pricing for the overage anyway.

A quick way to figure out which fits

1. Pull the last two seasons' individual-return counts and see how much they varied year over year.
2. If the swing is under roughly 15%, a capacity block is priced with real information behind it.
3. If the swing is wider than that, start with per-return pricing for a season and revisit once there's a volume pattern to reserve against.

What doesn't change between the two

Pricing model doesn't touch the review process. Every return, whether it was priced per-file or pulled against a reserved block, comes back to your firm for review before anything goes out. The engagement terms change; what your firm controls doesn't.
