You've outgrown your current Amazon analytics tool. The reports are slow, the data doesn't match Seller Central, and you're making decisions on numbers you don't fully trust. But switching feels risky. What happens to the 18 months of historical data you've built up? Will you start from scratch? The short answer: no. You can switch tools and keep every single day of your history. Here's exactly how.
Switching analytics tools isn't like switching email providers. Your Amazon data tells the story of your business: seasonal trends, fee changes, ad performance over time, margin shifts by SKU. Losing that context means losing your ability to compare this quarter to last year.
Three forces keep sellers locked into tools that no longer serve them:
The result? Sellers stay with tools that give them delayed data, inaccurate fee calculations, or clunky interfaces, all because switching feels harder than it actually is.
Sticking with an underperforming analytics tool isn't free. The costs compound quietly, month after month.
24h+
Some tools refresh data only once per day. That's a full business day of blind decisions on ad spend and pricing.
3-7%
Sellers using inaccurate P&L tools typically overestimate margins by 3-7%.
$2K-8K
Monthly revenue left on the table from SKUs that look profitable but aren't, identified only with accurate unit economics.
Every month you operate on inaccurate data, you're making reinvestment decisions based on wrong numbers. A SKU showing 22% margin might actually be at 15% after all fees. Over 12 months, that miscalculation compounds into thousands in misallocated ad spend and inventory purchases.
We built a done-for-you migration process specifically to remove the switching barrier. You don't need to touch a spreadsheet or run any scripts. Here's how it works:
Give us access to your current analytics tool, or export your historical data as a CSV or Excel file. Every major platform (Sellerboard, Helium 10, Jungle Scout, Sellersprite) supports data exports. If you're not sure how, our team will walk you through it.
Our team reingests your entire history into Nova. We map every field to Nova's data model, handle date formats, currency conversions, and fee categorization. You don't need to do anything during this step.
Once the ingestion is complete, we'll confirm what was imported: total rows, date range, and any fields that needed special handling. Compare a few spot-check numbers against your old tool. Once you're satisfied, you're done. Your Profit & Loss dashboard shows your complete history from day one.
Unlike API-based syncs that can only pull what Amazon still has available, our ingestion process preserves data that may have already aged out of Amazon's reporting window.
We'll walk you through the process, answer your questions, and get your historical data migrated with zero hassle.
Here's a breakdown of the core Amazon metrics we preserve during migration. Some come automatically from Amazon's API, while others depend on what you've tracked in your current tool.
| Metric | Source | Notes |
|---|---|---|
| Orders and Revenue | Amazon SP-API + your exports | API covers last 2 years. Older history preserved from your exports. |
| Units Sold | Amazon SP-API + your exports | Per-SKU and per-ASIN breakdowns retained. |
| FBA, Referral, and Other Amazon Fees | Amazon SP-API + your exports | All fee types preserved, including storage and removal fees. |
| Advertising Spend (SP, SB, SD) | Amazon Ads API + your exports | API provides recent data. Older campaign history preserved from exports. |
| COGS / Landed Costs | Your exports | Critical to migrate. Amazon doesn't store your costs. We preserve every entry. |
| Refunds and Returns | Amazon SP-API + your exports | Full refund history including partial refunds and return reasons. |
| Promotions and Coupons | Amazon SP-API + your exports | Promotional discounts and coupon costs preserved for accurate P&L. |
The key insight: COGS data is the most critical piece to migrate. Amazon's API doesn't provide your landed costs, so if you've spent months entering per-SKU costs into your current tool, that data lives only in their system. We preserve every COGS entry so your profit calculations remain accurate from day one.
