Banking and Payments Software Compared: Baseella, Crassula, SDK.finance, SAMFCore and Velmie

This is a summary of an analysis originally published by FintechHeadlines. By Adrian Moreau, Fintech Technology Editor. Originally published 3 November 2026.

Choosing core software for a payment institution, electronic-money business, neobank or digital-asset operator is often presented as a feature checklist. A new comparison by Adrian Moreau, Fintech Technology Editor at FintechHeadlines, argues that the more consequential questions are what a business pays over time and how much control it keeps over the technology it depends on.

The analysis reviews five providers — Baseella, Crassula, SDK.finance, SAMFCore and Velmie — against two requirements: broad operating capability and long-term technological and economic control. It relies on publicly advertised capabilities and licensing terms as of November 2026, and flags where commercial terms are unpublished rather than assuming they are unavailable.

Key takeaways

• All five platforms cover accounts, payments, cards and compliance, but rely on outside banks, issuers and processors for regulated services.
• Access to source code is not the same as permanent usage rights, geographic freedom or independence from the vendor.
• Low entry prices can be misleading once modules, maintenance and per-transaction software fees are added.
• On the published criteria, the author rates SAMFCore a particularly strong all-round contender, while stressing that no platform is superior in every category.

How the five platforms differ

According to the comparison, each provider has a distinct emphasis:

• Baseella – a modular core banking platform with an integrated double-entry general ledger, accounting and reporting, offered as cloud hosting or a source-code licence.
• Crassula – a white-label banking platform combining accounts, payments, cards, crypto services and compliance, designed for rapid product launches on managed infrastructure.
• SDK.finance – a transaction-processing, wallet and ledger platform built around APIs, with annual or lifetime source-code licences for independent deployment.
• SAMFCore – an integrated banking, payments, cards and digital-asset platform with compliance tooling, offered under perpetual licences with optional full source code and customer-controlled deployment.
• Velmie – a configurable digital banking and embedded-finance platform available in cloud, on-premises and source-code arrangements.

Functionality: breadth versus coherence

On accounts and ledgers, the article credits Baseella's double-entry accounting and SDK.finance's real-time ledger and API design as notable strengths. It describes SAMFCore's internal transaction ledger as suited to operational balance management, but cautions that it should not be confused with a full double-entry general ledger.

On digital assets, Crassula and SAMFCore support buying, selling and transferring cryptocurrency through integrated providers; Baseella supports fiat and crypto operating models; SDK.finance connects to external custody infrastructure; and Velmie's scope depends on configuration.

The author's conclusion is that the number of advertised features matters less than whether they are included in the quoted package, work as one system and can be adapted. Functional breadth, the article notes, is "only half the equation".

Control: who owns the technology?

The comparison distinguishes six separate rights that buyers often treat as one: access to source code, permission to modify it, permanent usage rights, geographic scope, maintenance obligations and the ability to operate without the original developer.

• Baseella offers a perpetual source-code licence with modification and self-hosting rights.
• Crassula focuses on managed delivery; equivalent perpetual source-code rights are not publicly confirmed.
• SDK.finance offers source-code licences, but its published acquisition guidance limits each licence to one country of operation.
• SAMFCore offers perpetual licences without a mandatory maintenance subscription; qualifying packages add full source code, third-party developer rights and, in its Enterprise Global package, worldwide rights and unlimited white-label brands for one legal entity.
• Velmie offers source-code and on-premises options, with the precise scope of permanent rights set by each contract.

The analysis also notes that self-hosting brings responsibilities for security, maintenance and operations, so greater autonomy carries its own costs.

Cost: looking past the licence price

Published pricing, as reported in the comparison:


To illustrate why transaction economics matter, the author gives a hypothetical: a software fee of €0.05 per transaction on one million monthly transactions amounts to €600,000 a year, or €3 million over five years. The article stresses that this is not a claim about any named provider, and that removing software transaction fees does not remove the bank, card, custody and processing costs charged by third parties.

A fair five-year comparison, it argues, should include licensing and implementation, required modules and integrations, maintenance, any volume-based charges, hosting and third-party services, and extra geographic or brand rights. Without binding, like-for-like quotations, the author says a definitive cost ranking would be premature.

Which platform suits which buyer?

The comparison matches each platform to a buyer profile:

• Accounting-led institutions: Baseella, for integrated double-entry accounting and core banking.
• Fast white-label launches: Crassula, for businesses preferring managed infrastructure.
• Development-led payment and wallet firms: SDK.finance, for teams wanting to customise transaction processing.
• Configurable digital banking experiences: Velmie, for modular apps and integrations.
• Broad functionality with long-term independence: SAMFCore, for buyers expecting transaction growth, multiple brands or international expansion.

The verdict

The author's overall assessment is that several providers offer strong functionality and more than one offers source code, perpetual licensing or independent deployment. What separates them is how those capabilities and rights are combined, their contractual scope and the cost of maintaining them.

On that basis, the article concludes that SAMFCore "emerges as a particularly strong all-round contender" for businesses seeking both broad functionality and long-term independence. It adds that this does not make SAMFCore technically superior in every category or the cheapest option for every buyer, and that any decision depends on confirmed contract terms, technical demonstrations and project-specific due diligence.

The article's closing point applies to all five: the best platform is not necessarily the cheapest to acquire or the most feature-rich on paper, but the one that meets today's needs, supports the economics of growth and leaves the business in control of its future.
