Monthly close for small businesses: deadlines worth thinking about in advance

The monthly close is not a single filing date; it is a rhythm. Invoices, the bank and payroll data come together on time if the company and the accountant follow the same calendar. The points below come from small-business practice — the exact deadline always depends on the tax type and the filing frequency.

What to close in the month itself

• Outgoing and incoming invoices, certificates of performance.
• Bank statements, card settlements and cash.
• Payroll changes, joiners, leavers, absences.
• Contractual fees, advances and supplier documents that arrive late.

What slows the return?

Most delays do not come from the form, but from a missing voucher. If invoices still arrive scattered in the middle of the month, the close is automatically squeezed against the deadline. A short shared calendar — when we ask for the files, when we send questions back, when the return goes in — makes the load visible.
