When a customer queries an invoice, finance needs the hours, fuel or quantities behind it. Connect those records before the bill is prepared.

GRA describes E-VAT as an electronic system for issuing VAT receipts, with a standalone option and an option for integration with an existing invoicing system. Its service page explains setup and receipt verification.
For an equipment, haulage or construction business, the daily task comes before the invoice: give finance a clear record of the hours, fuel or quantities being billed.
Connect each charge to the work
Start with the customer, contract or order, the relevant period and the agreed basis of the charge. Connect the supporting machine hours, fuel issue or measured quantity. Keep the review and any corrections with the entry.

Make queries easy to investigate
- For equipment hire: machine, hire dates, hours and agreed standby records.
- For supplied fuel: quantity, receiving asset, date and supporting issue record.
- For measured work: work item, location, quantity and supporting measurements.
- For a correction: the original entry, reason, reviewer and updated quantity.
When a customer asks about a charge, the office should be able to find the relevant record without chasing several people. Missing details can then be resolved before another invoice is prepared.
Follow a hire charge from the site to the invoice
Suppose the site reports ten days on hire and finance receives a customer query about two of them. Open the booking, dispatch and return dates, daily records and any standby instruction. Establish which days are chargeable under the agreement before changing the bill. The invoice total alone cannot explain that difference.
A fuel charge needs the same connection to its source. Match the receiving machine, issue date, quantity and agreed charging basis. For measured work, match the work item and the quantity used in the payment review. Giving each charge a stable reference lets site and finance discuss the same entry.
Keep corrections connected across the handover
When the site record changes, record who reviewed it, the reason and the revised quantity. Let finance know which charge is affected. Finance then follows the approved invoicing process for any invoice correction and keeps the resulting reference with the review. This avoids one team working from an amended quantity while the other still uses the earlier figure.
Use a short handover list before billing: entries ready to use, entries awaiting confirmation and charges under discussion. Each open entry needs an owner and a response date. A customer query then becomes a check against a known record instead of a new search through messages and notebooks.
Keep the operational and tax records easy to follow
The approved invoice identifies the transaction for the invoicing process. The site record explains the work behind the charge. Keep the customer, contract, period and source references consistent between them, and retain the supporting documents in a form the responsible team can retrieve.
For a business working across several Ghana sites, agree the handover before the month-end deadline. A contract with fuel deductions needs different supporting entries from a fixed-period equipment hire or a measured work item. The process should follow that difference rather than asking every site for the same undifferentiated total.
Give site and finance a shared handover
Agree which records finance needs and who checks them. Review missing quantities, disputed entries and unsupported adjustments before the billing deadline. This turns the handover into a repeatable process instead of a monthly search.
Where Darikoda fits
Darikoda connects the field records behind the charge. Finance uses those records alongside its approved invoicing and tax processes. Start with one contract and make the path from site entry to billing clear.
Review the record behind one invoice
Use the free 30-minute audit to follow one charge back to the site record. Leave with a one-page map of the gaps and practical priorities for your operation.
