A paper register can work for a small, stable customer list. A spreadsheet makes totals easier to calculate. A billing app connects customers, charges and receipts, but it still needs correct starting data. The best choice depends on the work you repeat and the mistakes you need to prevent.

An app is not automatically correct, and a spreadsheet is not automatically unreliable. A well-maintained system beats one nobody checks.
Choose a clean switch date
Finish one period in the old system and start the next in the new system where possible. Agree each customer's opening due or advance. Keep the old ledger as supporting evidence rather than deleting it after migration.
For example, Meera owes ₹320 on the switch date. Enter ₹320 as opening dues, then record only meals supplied after that date. If you also recreate the unpaid historical ₹320 invoice, you have doubled the amount unless your migration method explicitly reconciles the two.
Pilot before moving everyone
Choose a customer with a normal schedule and another with a skip or part payment. Add their meal rates and schedules in DAM, generate the appropriate records and compare closing balances with your original system. Check that lunch and dinner are not combined incorrectly.
Resolve naming duplicates before import or manual entry. A phone number can help identify an account, but shared family numbers need extra care. Preserve customer identities and document which old record became which new account.
Maintain the habit after migration
Record cash promptly, reconcile UPI receipts and review exceptions daily. Restrict who can change rates or delete records using the access options available in your plan. Back up or export important records using supported options, and verify that you can read them.

Can I run both systems during a trial?
Yes, briefly, for reconciliation. Decide which is the source of truth and avoid sending two conflicting statements to customers.
