If your compliance work runs on spreadsheets and email reminders, you already know how much time it eats. Logging consent, chasing data subject requests before the 30-day deadline, keeping a Record of Processing Activities current, proving to anyone who asks that the controls actually exist. Plenty of UK businesses lose hundreds of hours a year to it. Off-the-shelf GDPR tools are meant to fix that, but most come with their own fixed way of working, and you end up bending your process to fit theirs.
We build GDPR compliance tools around the way you actually handle data. The software is developed in the UK, it connects to the systems you already run, and it’s built for UK GDPR, the Data Protection Act 2018 and PECR. You pay once and own it. No per-user fees, no per-framework charges, no annual price hike to budget around.
Where off-the-shelf GDPR tools tend to let you down
The market is wide, but it’s also fragmented, and that fragmentation is the real problem. No single product does everything well.
- Audit-first platforms are strong on control evidence but thin on the privacy operations that take the daily effort - DSAR fulfilment, consent, data mapping. Manual work stays manual.
- Privacy-ops platforms handle DSARs and consent well but lack the depth for full audit readiness.
- Cookie consent tools are cheap and quick, but they only cover the banner. They don’t touch DSARs, data mapping or RoPA.
- Enterprise GRC suites cover almost everything, but the pricing is opaque, the onboarding is heavy, and they assume you have a dedicated compliance team to run them.
So most businesses end up paying for two or three tools, stitching them together by hand, and still falling back to spreadsheets for the gaps. A few specific failure points come up again and again:
- Pricing scales with headcount, frameworks or request volume, so the bill climbs as you grow - bill shock at 200-plus employees is common
- Generic connectors don’t reach legacy systems or internal databases, so DSAR responses come back incomplete
- Bulk DSAR discovery hits API rate limits, and fulfilment slips past the 30-day deadline
- Consent gets logged without a timestamp, version or proof of withdrawal, which means it won’t survive an audit
- Workflows assume a standard path and can’t encode your own rules, so people build workarounds
The risk underneath all of it is that something falls through a gap and the ICO ends up asking about it. Serious failures - denial of rights, no lawful basis, no DPIA where one was needed - carry fines of up to £17.5 million or 4% of annual turnover.
What working with ByteGears looks like
We’re a small team, so the work fits the business rather than the other way around.
We start by mapping how you collect, store and share personal data now - the systems, the vendors, the flows - before any code gets written. That mapping isn’t just discovery; it becomes the backbone of your RoPA. We build for UK GDPR, the DPA 2018 and PECR, and we know where they differ from EU GDPR.
The system connects directly to the tools you already run, so you’re not copying data between platforms by hand. Where a system has no API - an older ERP, an on-premises database, an internal app - we build the bridge to reach it, because that’s usually where DSARs go wrong. You replace recurring SaaS fees with a fixed-cost system you own outright. And because you own the code, when the guidance shifts you adapt the system in weeks instead of waiting on a vendor’s roadmap. Support comes from developers in the UK.
Features we typically build
The system is organised around the entities GDPR actually cares about - processing activities, data categories, data subjects, legal bases, vendors, consent records, DSARs, DPIAs and breach logs - so the documentation falls out of normal use rather than being maintained on the side.
Consent and preference management
Audit-grade consent logging with timestamp, consent version and proof of withdrawal. Granular choices across marketing, analytics and profiling, with cookie banner deployment and renewal reminders.
Data subject request handling
Intake form, identity verification, automated discovery across connected systems, response compilation and secure delivery - all tracked against the 30-day deadline. Conditional logic where you need it, so a request can route through approval or staged deletion rather than a single fixed path.
Data mapping, inventory and RoPA
A visual view of where personal data lives and how it flows, with retention periods and risk scoring. A Record of Processing Activities that stays current as a by-product of the mapping, ready for an Article 30 audit.
Breach and incident logging
Structured incident records and notification tooling built around the 72-hour reporting window, capturing affected data categories, systems and subject counts.
DPIA workflows
Guided risk assessments for high-risk processing, with documented mitigations and sign-off.
Vendor and processor monitoring
A processor inventory with DPA status tracking, subprocessor lists, compliance questionnaires and alerts when contracts come up for renewal.
Compliance dashboard and reporting
Live compliance status, DSAR metrics, and audit evidence exported in the format your auditor actually asks for.
Role-based access controls
Permissions set so staff only see the data their job calls for.
International transfer handling
Logging of the transfer mechanism - adequacy, SCCs, transfer impact assessment - for each cross-border flow.
Integrations
Two-way sync with CRM, marketing, HR and accounting systems through APIs and webhooks, plus custom connectors for systems with no API.
How a project runs
Discovery and planning (2-4 weeks)
Workshops to map your data flows, systems and vendors, work out what’s obligatory for you, and surface any shadow IT before it becomes a gap later.
Development (6-12 weeks)
Built in short cycles with a progress review every fortnight. We deliver a usable core first - consent logging, DSAR intake and fulfilment, and an inventory of your top systems - then phase in fuller data mapping, vendor risk and DPIA workflows.
Testing and deployment (2-3 weeks)
Security testing, plus a period running alongside your existing process before the switch, so audit continuity isn’t broken.
Training and support
Training tailored by role - a DPO needs different things from the system than support staff handling DSAR intake - then 12 months of support included, with retained packages available after that.
What it costs
Custom development costs more upfront than a SaaS subscription. Over a few years the maths tends to favour owning the thing:
- No per-user, per-framework or per-DSAR charges, so cost doesn’t climb as you grow or take on another regulation
- A single upfront build plus modest annual maintenance, instead of a subscription that renews higher each year
- When regulations change, you adapt the system yourself rather than waiting on a vendor
- You hold the intellectual property rights to the software
For a mid-sized business with steady growth, a custom build often reaches cost parity with a mid-market GDPR SaaS subscription somewhere around year three or four - sooner if you have unusual workflows, high DSAR volume, or legacy systems that off-the-shelf tools can’t integrate without expensive custom connector work anyway. The figure depends on how complex your requirements are, but after discovery you get a fixed quote rather than a moving target. Book a free consultation and we’ll give you a ballpark for what you have in mind.
To be straight about it: if your needs are simple - a single data type, a handful of well-connected SaaS tools, standard cookie consent - an off-the-shelf product is probably enough, and we’ll tell you so. Custom makes sense when your workflows are non-standard, your data is spread across systems generic connectors can’t reach, or you’re juggling GDPR alongside sector rules.

Common Questions About Custom GDPR Compliance Management Tools
How does a custom build compare on cost to GDPR SaaS?
A custom build costs more upfront, but it doesn't scale with headcount, frameworks or DSAR volume. Off-the-shelf GDPR platforms commonly charge per user, per regulation, or per request, so the bill climbs as you grow. For a mid-sized business with steady growth, a custom system often reaches cost parity with a mid-market SaaS subscription by around year three or four, and you avoid the annual price increases that come with renewal. We give you a fixed quote after discovery rather than a moving target.
What's a realistic development timeline?
Most projects reach production in three to six months. We usually deliver a working core first - consent logging, a DSAR intake and fulfilment workflow, and a data inventory of your main systems - then phase in fuller data mapping, vendor risk and DPIA workflows. Complex environments with many legacy systems or multiple jurisdictions can take longer, and we'll be straight with you about that at discovery.
Can it pull data from our older systems for DSARs?
Yes, and this is often the main reason a custom build makes sense. Off-the-shelf tools rely on pre-built connectors and struggle when data sits in an on-premises database, a legacy ERP or an internal application with no API. We build the middleware to reach those systems so a data subject access request can be answered fully within the 30-day deadline rather than partially.
Which systems do you typically integrate with?
Common connections include CRM (Salesforce, HubSpot, Pipedrive), marketing platforms, HR and identity systems (Microsoft Entra ID, Okta), email (Microsoft 365, Google Workspace), e-commerce and payments (Shopify, Stripe), and accounting tools (Xero, Sage, QuickBooks). We connect through APIs and webhooks where they exist, and build custom integrations for systems that don't expose one.
How do you handle hosting and data residency?
We host within the UK or EU by default. GDPR doesn't mandate EU data residency, but keeping data in the UK or EU avoids the need for Standard Contractual Clauses and transfer impact assessments, which keeps your compliance position simpler. The UK currently holds an EU adequacy decision; if you do transfer data to third countries, the system can log the transfer mechanism for each flow.
What about updates when the rules change?
GDPR guidance and enforcement keep moving, and SaaS vendors are often slow to reflect new ICO or EDPB expectations. Because you own the code, changes - a new consent flow, an extra audit field, a report in the format an auditor actually wants - can be made in weeks rather than waiting on a vendor roadmap. Builds include 12 months of support, with retained packages available after that.
