Native to Cross-platform
Two native apps become one maintainable codebase.
ERPHUBs migrates separate native iOS and Android apps to Flutter or React Native, preserving features, data and user accounts while cutting the cost of maintaining two codebases.

Why It Matters
Why Native to Cross-platform Needs a Specialist Approach
Two native codebases double cost and slow every feature. Moving to Flutter or React Native can unify them, but only if behaviour, data and users move safely. We migrate in stages so the live app keeps running throughout.

Bottlenecks and Fixes
Where Native to Cross-platform Projects Get Stuck, and How We Design Around It
Double maintenance
The bottleneck. Every change is built twice.
How we design it. A single codebase with shared logic and tests.
Target result: 0 data loss target
Feature drift
The bottleneck. iOS and Android diverge.
How we design it. Parity matrix and shared acceptance tests.
Target result: Minutes typical cut-over downtime
Migration risk
The bottleneck. Rewrites lose features or users.
How we design it. Strangler approach: migrate screens gradually inside the existing app.
Target result: 100% feature parity checked
By Industry
Native to Cross-platform: Bottlenecks We Solve, Industry by Industry
Every sector hits different walls. Here is what we see and how we design around it.
Retail
Bottleneck: Seasonal releases are hard to sync.
Our design: Shared catalogue and checkout modules released together.
Banking
Bottleneck: Security must not regress.
Our design: Keep native security modules while moving UI.
Media
Bottleneck: Features land late on one platform.
Our design: Common feed and player components.
Healthcare
Bottleneck: Validated flows cannot break.
Our design: Regression suites against clinical screens.
Migration Risk Control
Migration Risks and How We Remove Them
Migrations fail in predictable ways. We plan for each one before the first record moves.
Data loss or corruption
The risk. Records are altered or dropped during transfer.
Our safeguard. Checksums, record counts and sampled comparisons at every trial load.
Extended downtime
The risk. Users locked out during the switch.
Our safeguard. Continuous replication and a rehearsed, time-boxed cut-over.
Feature regressions
The risk. Behaviour differs from the old app.
Our safeguard. Automated regression suite and side-by-side user acceptance tests.
Lost reviews and users
The risk. Store changes reset ratings or break updates.
Our safeguard. Same bundle IDs, transfer-safe processes and staged rollouts.
Security gaps
The risk. New environment is configured loosely.
Our safeguard. Hardened landing zone, secrets management and access reviews.
Cost overruns
The risk. Cloud or licence costs exceed forecasts.
Our safeguard. Right-sizing, budgets and alerts from the first week.

Standards We Build To
Quality, Security and Compliance in Native to Cross-platform
Record-level reconciliation
Counts, checksums and samples compared between old and new.
Rehearsed cut-over
At least one full dress rehearsal before go-live.
Security and compliance
Encrypted transfer, access control and audit logs.
User continuity
Accounts, sessions and settings carried across.
Planning
What Affects Timeline and Cost in Native to Cross-platform
Typically 4 to 16 weeks depending on size, data volume and downtime limits.
Size and age of the system
Older, larger systems need deeper discovery.
Data volume
Large datasets need staged or replicated loads.
Downtime tolerance
Zero-downtime plans add engineering effort.
Third-party dependencies
Every library and integration must be replaced or re-tested.

Africa
Native to Cross-platform: what Africa teams should plan for
Moving to Zoho from another system in Africa means mapping tax codes, currency and opening balances correctly the first time, then switching over between filing deadlines.
Cutover timed to your calendar
We avoid the busy filing windows: South Africa: month after period end: VAT201 via SARS eFiling; Kenya: 20th of the following month: VAT return on KRA iTax.
VAT (country-specific) code mapping
Existing tax codes are matched to VAT (country-specific) (ZA 15%, NG 7.5%, KE 16%, EG 14% standard) in the Zoho Books (South Africa and Kenya editions where available).
Where your data lives
Your Zoho account is created on the Nearest data centre (EU/US/IN) per customer need (zoho.com).
Moves we see most here
Typical sources in Africa: Sage / Pastel, QuickBooks, Tally, Excel.
Yes. The Africa team configures it with the Zoho Books (South Africa and Kenya editions where available), USD and VAT (country-specific), and supports it Mon-Fri 09:00-18:00 CAT.
Zoho accounts for Africa use the Nearest data centre (EU/US/IN) per customer need (zoho.com). We confirm the data centre with you before any migration or integration starts.
