Creating a fast, accurate invoice

1. Start a new invoice and choose a template.
2. Select client from the address book (auto-fills billing details).
3. Add items from your product/service list or create ad-hoc line items:
   • Enter quantity, unit price, and select tax rate. The system will calculate line totals automatically.
4. Apply discounts or surcharges at line-level or invoice-level.
5. Confirm payment terms, due date, and any notes (e.g., late fee policy).
6. Preview the invoice to check formatting, calculations, and tax breakdown.
7. Save as draft, send immediately by email, or export as PDF.

Tips for speed:

• Use keyboard shortcuts (if provided) and templates for recurring invoices.
• Clone previous invoices for repeat jobs or retainers.
• Import clients and products in bulk via CSV to avoid manual entry.

Ensuring billing accuracy

• Verify tax settings per client location to avoid under-/over-charging.
• Use automatic rounding rules that match your accounting standards.
• Double-check currency and exchange rate settings for international clients.
• Enable validations (required fields) to avoid missing information like invoice number or due date.
• Reconcile payments by marking invoices paid and recording partial payments with dates and payment methods.

Automating recurring billing and reminders

GT Invoice Maker typically supports:

• Recurring invoices for subscriptions or retainer services — schedule weekly, monthly, quarterly, or custom intervals.
• Automatic email reminders for upcoming and overdue invoices — customize timing and message templates.
• Auto-apply late fees or interest after a grace period.

Automation reduces manual follow-up and helps maintain steady cash flow.

Customization and branding

• Choose from multiple templates or build one with your logo, brand colors, and custom fonts.
• Add custom fields (purchase order numbers, project codes) to line items or invoice headers/footers.
• Localize invoice language and number/date formats for international clients.

Well-branded invoices reinforce professionalism and reduce client confusion.

Integrations and exports

• Sync with accounting software (QuickBooks, Xero) to keep ledgers up to date.
• Export invoices and client lists as CSV for bulk analysis or backups.
• Connect payment gateways (Stripe, PayPal) to accept card payments directly from invoices.
• Use Zapier or webhooks for custom integrations with CRMs and project management tools.

Integrations cut down duplicate data entry and speed up reconciliation.

Security and backups

• Keep a backup strategy: export important invoices and client data periodically.
• Use strong account passwords and enable two-factor authentication (if available).
• Limit team access with role-based permissions; restrict who can edit templates or issue credits.

Troubleshooting common issues

• Wrong tax calculation: Check client tax-exempt status and tax rate assignments.
• Duplicate invoices: Confirm invoice numbering settings and avoid manual number overrides.
• Missing logo or formatting changes: Re-upload logo file and clear browser cache or regenerate the template.
• Payment reconciliation mismatch: Verify payment date, amount, and currency; check for refunds or chargebacks.

Best practices checklist

• Keep client data updated (addresses, tax IDs).
• Use consistent invoice numbering and retain archived copies.
• Send invoices promptly — same day or within 24–48 hours of service completion.
• Enable online payments to shorten the payment cycle.
