Why Zoho Books Struggles with Deposit Taxes on Retainer Invoices

Zoho Books excels at automated invoicing, multi-currency support, and integrations, but its retainer invoice feature—meant for advance payments—taxes the entire project amount upfront, not just the deposit (e.g., 50%). This differs from Wave, where taxes pro-rate to the deposit only, creating a smoother experience.

  1. Tax Overcalculation: Sales tax applies to the full retainer, leading to excess upfront charges.
  2. Payment Friction: Zoho's flow involves extra steps like viewing invoices before paying, unlike Wave's direct links.
  3. Customer Confusion: Clients see bloated amounts, eroding trust in service industries.

Recent 2025 updates improved tax automation for global compliance (e.g., VAT handling), but deposit-specific pro-rating remains a gap. No worries—Zoho's flexibility shines with these verified workarounds. For a deeper dive into Zoho Books basics, explore our Zoho Books overview.

Immediate Solutions for Accurate Deposit Taxes

Solution 1: Standard Invoices with Partial Payments (Recommended Starter)

Ditch retainers for standard invoices that support partial payments. Taxes calculate on the full amount, but you collect only the deposit portion—proportional tax included.

  • Create a full-project invoice with line items and standard taxes.
  • Enable "Allow Partial Payments" in invoice settings.
  • Set terms noting the 50% deposit requirement.
  • Record the deposit as a partial payment (e.g., 50% of total, including tax).
  • Invoice the balance later or track via the original.

Solution 2: Two Separate Invoices for Deposits and Balance

Split into a deposit invoice (taxed on 50%) and a balance invoice. This mirrors Wave's approach and provides a clean audit trail.

  • Invoice 1 (Deposit): Line item: "Deposit for [Project] - 50%"; apply taxes to this amount only. Add note: "Balance due on completion."
  • Send and collect via Zoho gateways.
  • Invoice 2 (Balance): Post-service, create for remaining 50% with taxes; reference Invoice 1.
  • Use templates for consistency.

Solution 3: Estimates with Online Payment Links

Use estimates for quotes, enable payments, and convert to invoices post-deposit. This reduces formal invoicing until needed.

  • Create full-project estimate with taxes.
  • Enable "Online Payments" in settings.
  • Customer pays deposit directly from the estimate link.
  • Convert to invoice; Zoho applies the payment.

Workflow Optimizations to Match Wave's Simplicity

Solution 4: Customer Portal for Saved Payments

Let clients self-serve via a branded portal—view invoices, save cards, pay in one click.

  • Activate in Settings > Customer Portal.
  • Invite clients (one-time account).
  • Link portal in emails for repeat ease.

Solution 5: Payment Links for Direct Access

Bypass invoice views with standalone links—customers pay instantly.

  • Generate from any invoice/estimate.
  • Embed in emails (auto-fills details via Zoho).
  • Track payments in real-time.

Advanced Technical Workarounds (Caution Advised)

Solution 6: Custom Tax Rates for Deposits

Create a halved tax rate for deposits only—but this risks audits.

  • Settings > Taxes > New Tax (e.g., 50% of standard rate).
  • Apply to deposit invoices; use full rate for balances.
  • Document for taxes.

Solution 7: Sales Orders with Deposit Tracking

Track full projects via sales orders, generating partial invoices.

  • Create sales order for full amount; add deposit field.
  • Generate 50% deposit invoice (taxed accordingly).
  • Invoice balance from the order.

  • Integrate via Zoho (native for Stripe).
  • Create links in processor; record in Zoho manually or via Zapier.
