Support Ticketing System for SaaS and B2B Teams
A ticketing system for support built for SaaS and B2B teams — captures every email, chat, call and form into one queue, routes by priority and SLA, escalates before deadlines. Custom alternative to Zendesk and Freshdesk, without per-seat monthly fees.
What the support ticketing system includes
Omnichannel intake — email, chat, phone, form
Email-to-ticket gateway turns every support@ message into a ticket. Live chat widget, telephony via Asterisk or 3CX, embedded portal form. One inbox, one ticket ID, regardless of channel.
Routing by category and SLA
Rules engine assigns each ticket by topic, product, language or customer tier. Premium SLA clients hit the priority queue with 15-minute first response; trial users wait standard hours.
Queues, escalation and SLA-driven support
SLA timers for first response and resolution with visual warning at 75% of deadline. On breach tickets escalate to a senior agent, with a parallel alert to the account manager for enterprise.
Knowledge base and AI suggested replies
Built-in knowledge base, public and internal articles. The AI helpdesk assistant reads a ticket and proposes top-three answers with a citation. Cuts first response time by 40%+ on typical cases.
CSAT score and follow-up automations
On ticket closure — automatic CSAT survey with 1-5 score and comment. Data ties to agent, queue, product and time of day. Auto-reopen if the customer replies within seven days.
Slack, Teams and CRM integration
Side-channel notification in Slack or Teams, slash command to reply from chat. Two-way sync with HubSpot, Salesforce or custom CRM — ticket history on the contact card.
Reports — first response, resolution, backlog
Real-time dashboard for first response, resolution time, backlog per queue, SLA breach rate and agent load. Export to Metabase, Power BI or Looker.
Who it's for
SaaS companies
Product teams with steady support volume — bugs, how-to, billing. Ticket links to user ID with plan, last login and feature usage. Jira or Linear integration for engineering handoff.
Internal IT support
In-house IT helpdesk at mid and large companies — access, laptops, VPN, password resets. Categories by issue type, asset linking, ITIL-aligned change and incident workflows.
MSPs — managed service providers
IT providers supporting dozens of end clients under different SLAs. Multi-tenant architecture, time-on-ticket billing, RMM integration. White-label portal per client.
How we build the custom helpdesk
1. Discovery — flows, SLAs, volume
We map intake channels, daily volume, peak hours, ticket types and SLAs. Output is a spec for queues, routing rules and handoff between tier 1, 2 and 3 — before any code is written.
2. Stack — Next.js, PostgreSQL, email gateway
Next.js 15 with React server components, PostgreSQL for tickets and SLA timers, Redis for the queue. Email gateway via Postmark or SendGrid Inbound Parse, WebSocket for live chat.
3. Build, SSO, CRM integration
Workflow engine, RBAC, SSO (Google Workspace, Microsoft Entra ID), CRM integration to HubSpot or Salesforce. AI suggesting layer with GPT-4 or Claude over the knowledge base.
4. Migration, training, support
We import historical tickets from Zendesk, Freshdesk or Jira Service Management. Two or three training sessions, two weeks of parallel running. Business-hours SLA after launch.

Frequently Asked Questions
Why a custom ticketing system instead of Zendesk or Freshdesk?
Past 15 agents Zendesk and Freshdesk cost €1,500-€3,000 per month in license fees alone, before AI or voice add-ons. A custom helpdesk is a one-time investment that pays back in 14-20 months, gives you full ownership of data and integrations, and never locks you to a vendor roadmap. You own the code — adding a field or workflow takes days, not a vendor release quarter.
Can a customer open a ticket by replying to an email?
Yes — email-to-ticket is standard. A customer writes to support@your-domain and the system creates a ticket, matches a known contact by address, attaches files and starts the SLA timer. Agent replies go out from the same address, so the customer uses plain email without being forced into a portal login. Threading stays correct even across long conversations.
Does it suggest replies with AI?
Yes — we embed an LLM layer (GPT-4 or Claude, your choice) that reads the ticket, searches the knowledge base and proposes a draft reply with citation. The agent edits or accepts with one click. For 60-70% of repeat queries this saves 3-5 minutes per ticket. The AI is grounded on your own history, not public data, and respects GDPR processing rules.
How much does a support ticketing system cost?
A base custom helpdesk with email gateway, queues, SLA timers and core reports starts at €4,200. Mid-complexity rollouts with AI suggesting, omnichannel intake, SSO and CRM integration usually run €9,000-€18,000. Enterprise builds with multi-tenant architecture for MSPs, voice integration and custom billing can reach €30,000-€55,000. No per-seat license fees — only hosting and ongoing support.
