Migrating from Harvest to Tillage: a complete guide

Love Harvest’s time tracking but wish it had better quoting and contract features? You’re not alone.

Tillage complements Harvest (or replaces its invoicing) with intelligent quoting, contract generation, and automated invoicing. And migrating your data is painless.

If you’re here because of Harvest’s 2026 pricing changes, this guide focuses on the quoting-and-invoicing side of your stack — the part Harvest was always thinner on. You can keep Harvest for time tracking and layer Tillage on top, or migrate your billing fully.

Why Agencies are Switching

Harvest is great for time tracking, but falls short for:

• Quoting: Harvest has estimates, but no AI quote generation
• Built-in profitability tools: No variance buffers or margin on estimates
• Contract automation: No contracts or e-signatures
• Payment schedules: No milestone schedules, so a 50/25/25 project means copying invoices by hand
• Payment fees: No way to let clients cover processing fees

Tillage fills these gaps while preserving everything you love about Harvest.

Total time: Usually 10-15 minutes

Smart Features During Import

Duplicate Prevention

Tillage tracks Harvest source IDs to prevent duplicates. Run the import multiple times without creating duplicates.

Recurring Detection

If you’ve been manually creating the same invoice every month in Harvest, Tillage:

• Detects the pattern automatically
• Calculates your MRR
• Sets up automatic future generation
• Saves you hours of manual work

Data Preservation

All original Harvest data is preserved:

• Invoice numbers stay the same
• Dates remain unchanged
• Line item details intact
• Client information complete

What Happens to Harvest?

You have options:

Option 1: Keep Both

• Continue time tracking in Harvest
• Use Tillage for quoting, contracts, and invoicing
• Re-run the Harvest import whenever you want to pull in new clients or invoices (there’s no automatic ongoing sync)

Option 2: Full Migration

• Move your quoting, contracts and invoicing completely to Tillage
• Tillage doesn’t track time, so if you bill from timesheets, move time tracking to a dedicated tool
• Export remaining data from Harvest for records

Option 3: Hybrid Approach

• Keep Harvest for historical time data
• Start new projects in Tillage
• Gradually phase out Harvest

Common Questions

Will I lose any data?
No. The import is additive only. Your Harvest data remains untouched.

Can I import again if I mess up?
Yes. Duplicate detection ensures you won’t create duplicates.

What if I’m still using Harvest?
Keep using it! Many agencies use both. Tillage complements Harvest’s time tracking with better quoting and contracts.

How much does it cost?
The Harvest import is included free. Tillage is $0/month, and you can import unlimited clients and invoices.
