Books closed every month

Inkle Books auto-categorizes 90% of your transactions. A dedicated accountant reviews every close before it reaches you. You get accrual-basis books, clean reconciliations, and real-time cash flow, so when an investor asks for financials, you send them instead of rebuilding a year of history.

Never miss a filing, never eat a penalty

Inkle Tax predicts and tracks every federal, state, and Delaware Franchise Tax deadline from your entity details, and calculates your quarterly estimated tax from your actual books, so an underpayment penalty never catches you off guard. Licensed tax experts prepare and e-file: 1120, 7004, 1099, and the rest.

The startup edge cases, handled

R&D tax credits claimed end to end, startups get around $21,000 back a year on average. 409A valuations, Delaware Franchise Tax, multi-entity structures, and 5472s for foreign-owned entities: the things a generic bookkeeper gets wrong and a startup can't afford to.

Questions founders bring us

When's my Delaware Franchise Tax due, and how much?

My lead wants last year's financials by Friday.

Do we qualify for the R&D credit, and can you file it?

We're a Delaware C-Corp owned from UK. What do we owe the IRS?

Software alone can't answer these, and a spreadsheet bookkeeper won't. A dedicated tax expert does, over chat, with a 24-hour response SLA.

Incredible software and an extremely detail-oriented team. A must-have for founders wanting to save time without sacrificing quality
