Common questions about customer records
Short answers for people deciding whether CalCal is enough for their everyday records.
Do I need accounting knowledge?
No. CalCal is designed around plain records and a calendar-style workflow, so you can keep customer income organised without accounting jargon.
Is this only for landlords?
It is especially useful for landlords tracking rent and tenants, but it can also help simple sole traders keep customer-linked income tidy.
Can I use it for tax returns?
Yes. Better customer and income records make it easier to review figures before Self Assessment or MTD submission.
Does it replace a full CRM?
No. It is intentionally lighter: a practical customer record inside your bookkeeping flow, not a sales pipeline system.
Ready to tidy up the customer side?
Start keeping customer income where your tax records can actually use it.
CalCal helps you record customer-linked income in a simple, calendar-first way, then keeps those records available when tax time comes round.
