Marketplace ROI calculator

How much is your marketplace leaving on the table?

Four inputs. The estimate is vendor-published figures (GETIDA, Mastercard, industry analyses), not a benchmark. The honest version is the one you can defend in front of your CFO.

Your inputs

Honest boundary: All figures are vendor-published ranges or industry estimates, not a benchmark. GETIDA's 1-3% figure refers to FBA reimbursements, not GMV. Mastercard's $128/chargeback is an industry average. The calculator does not produce a benchmark.

Estimated annual exposure

$0per year
  • Unclaimed FBA reimbursements: $0 per year. GETIDA-published range: 1-3% of annual FBA reimbursements sit unclaimed. We use 2% as midpoint. Vendor-published, not independently audited.
  • Chargeback exposure: $0 per year (count × amount). Mastercard industry average: $128/chargeback. Friendly fraud represents ~75% of chargebacks (industry estimate).
  • Reconciliation labor: $0 per year (hours/month × 12 × loaded cost).

Estimated with Syntheka (outcome-aligned pricing option)

$0net annual effect
  • Recovery: Syntheka identifies reimbursement gaps and chargeback counter-attack opportunities. Industry estimates: 60-80% of identified gaps are recoverable with verified claims. Customer confirms every claim before invoice (Zendesk verified mode per W2).
  • Labor reduction: Industry estimate: 70% reduction in reconciliation hours. The remainder goes to verifying claims, not to confirming status.
  • Pricing: Syntheka's pricing is fixed-tier ($500/mo Starter, $2,000/mo Professional) plus an outcome-aligned option for verified recoveries (per-claim, customer-verified). We do not bill on assumed resolution.
  • Outcome-aligned estimate: $0 per year (mid-case). The range is wide because the recovery rate depends on your specific marketplace mix and your specific claim eligibility.

Honest boundary: The recovery rate is an industry estimate, not an audited customer deployment. It is the upper bound of the case a Syntheka pilot is built to test. The pilot itself produces the real numbers for your environment. We do not bill on assumed resolution; every claim is customer-verified before the invoice.

What the pilot produces

The pilot is where the numbers become real.

The calculator above is the upper-bound case for Syntheka. The pilot ends where you replace the estimates with measured values from your own accounts.

  1. Weeks 1-2: Connect your accounts (Amazon SP-API, bank statements, chargeback queue). Syntheka runs in shadow mode.
  2. Weeks 3-4: Syntheka surfaces reimbursement gaps and chargeback counter-attack opportunities. Customer confirms each.
  3. Weeks 5-6: Run shadow invoicing. Verified claims are listed; nothing is filed automatically.
  4. Weeks 7-8: Report. The pilot produces the actual reimbursement recovery, the actual chargeback win rate uplift, the actual labor saved. The decision to adopt, extend, or end is yours with the measured comparison data.
