On our homepage we make one claim against the field: none of the leading tools a Shopify seller might use for bookkeeping, per-order profit, or sales tax cites the IRS code section behind a transaction categorization. A claim like that is worthless if you cannot check it. This page is the check: every tool we reviewed, when, how, and what would make us retract it.
What we did: in June 2026 we reviewed the published pricing and feature pages of 18 tools across four jobs — per-order profit, full P&L, sales-tax nexus tracking, and IRS code-section citations on transactions. In July 2026 we re-checked the citation claim when QuickBooks shipped an AI deduction feature (it finds missing deductions and maps them to Schedule C; it does not cite code sections). What we did not do: run a paid trial of all 18 products. If a vendor ships this feature without ever mentioning it on their own pages, we would miss it — and we would want to know. See the correction offer below.

NOT FOUND means exactly that: no IRS code-section citation feature appears anywhere on the vendor's published pricing or feature pages as of the review dates, and none advertises one. It does not mean the tool is bad — most of these are good at the job they are built for, and several are ones we would point you to for that job. Bench is not in the table: it shut down in December 2024.
"Advertising expense" is a guess you defend at tax time. "§162, ordinary and necessary, Pub. 535" is a categorization your CPA can work from and an answer you can stand behind if anyone ever asks. Profenor cites the code section behind every expense — you can see the approach today, free, in the deduction checker: 153 e-commerce expense types, each with the code section behind it.
REVIEW DATES: initial review JUNE 2026; citation claim re-checked JULY 2026. Method: each vendor's own published pricing and feature pages. Vendor pages change — check them yourself before deciding anything; that is the point of publishing this. This page does not quote vendor prices, deliberately: prices move faster than claims, and the dated cost comparison on the homepage carries its own check dates.
