FD SDK Pricing: Costs and Commercial Models to Compare

There is no useful one-number answer to “How much does an FD SDK cost?” because providers can package implementation, software, issuer access, operations, and support differently. A fair comparison converts every proposal into the same volume assumptions and total-cost model.

Common FD SDK pricing components

An FD SDK or fixed deposit API proposal may include some combination of:

• One-time implementation or onboarding fees
• Recurring platform or licence fees
• Per-application, per-booking, or usage-based charges
• Revenue-share arrangements
• Minimum volume or commercial commitments
• Custom design, workflow, reporting, or issuer work
• Premium support or dedicated operating coverage
• Third-party KYC, verification, messaging, or payment costs

Ask whether quoted fees include taxes and third-party pass-through charges, and whether unsuccessful, abandoned, reversed, or repeated transactions are billable.

Compare the same scope

A low API price can be misleading if the distributor must build the customer journey, normalize every issuer, operate reconciliation, manage servicing, and maintain changes. Conversely, a full white-label SDK may include interface and orchestration capabilities that a team already owns.

Define the required scope before comparing proposals: issuer coverage, SDK or API model, KYC and payment workflow, theming, booking states, portfolio, maturity, withdrawal, reporting, reconciliation, support, and launch assistance.

The FD API integration guide explains the engineering work behind a direct API model. The white-label architecture guide explains the packaged SDK model.

Model total cost of ownership

Evaluate at least a 12- to 24-month period. Include internal engineering, product, design, security, compliance, operations, support, and issuer-management effort—not only the vendor invoice.

Model several realistic scenarios:

1. Expected monthly eligible users
2. Product-view to application-start conversion
3. Application completion and successful booking rate
4. Average deposit amount and issuer mix
5. Support and exception volume
6. Engineering effort for launch and ongoing change
7. Commercial revenue under each provider model

Run conservative, expected, and high-volume cases. This exposes minimum commitments that look inexpensive at scale but are costly during rollout.

Questions for a provider proposal

• Which services and issuer connections are included?
• Are sandbox, certification, and production launch included?
• What events create a billable unit?
• How are failed or reversed bookings treated?
• Are KYC, payment, messaging, and support costs included?
• What customisation is standard versus separately charged?
• Are there minimums, ramp periods, or renewal changes?
• What SLA and support coverage accompanies each tier?
• How are new issuers, features, and versions priced?
• What happens to commercials if volume or scope changes?

Price is only one evaluation dimension

Commercials should be evaluated alongside live issuer availability, customer experience, lifecycle depth, security evidence, documentation, sandbox quality, reconciliation, support, and change management. The cheapest quoted integration can become the most expensive option if it creates substantial operating work or slows launch.
