What is Yelken360?

A modular business platform that grows with you

Yelken360 is an ERP-style platform made of modules. You enable what you need today and add more as your business grows. New modules are added to the platform on an ongoing basis.

ERP, Catalog, Stock, Inventory, Invoicing, Accounting, CRM, HR, Integrations and more

One platform

All your business areas in one place: Catalog, Stock, Inventory, Invoicing, Accounting, CRM, HR and reporting. Modules work together; data stays unified.

Workspaces

Separate teams, brands or projects in one account. Each workspace has its own data and subscription.

Modular by design

Enable only the modules you need: ERP, Catalog, Stock, Inventory, Invoicing, Accounting, CRM, HR, Integrations and others. New modules are added regularly.

Plans that scale

Ready-made or custom plans. Set limits per module, pay for what you use, upgrade or add modules anytime.

Modules that simplify your work

ERP, Catalog, Stock, Inventory, Invoicing, Accounting, CRM, HR, Integrations and more. Enable the modules you need under one subscription; new modules are added to the platform over time.

  • Opportunity management

    Select a customer, set title and amount, expected close, and owner. Filter the list by stage, amount, or date to see exactly where each deal sits.

  • Pipeline stages

    Model your sales process with custom stages. Bootstrap from a template or build your own, order them, assign colors, and flag won/lost stages for reporting.

  • Activities: call, meeting, task, note

    Record every interaction with subject and optional due date. Activities appear in chronological order on the opportunity; complete tasks when done.

  • Timeline and opportunity detail

    See customer, stage, amount, notes, and the full activity history on one screen so gaps in follow-up are obvious.

Review now

Features

  • Employee management

    Core HR fields: name, employee number, contact, branch/department/position, hire and exit dates, avatar, optional user mapping (link existing user or invite by email). Detail pages show timelines of rewards, warnings, complaints, transfers, documents, and leave.

  • Organization structure

    Branches, hierarchical departments, and positions managed via settings modals. Departments nest parent/child; positions belong to departments. Lists and reports filter through this tree.

  • Document types and employee files

    Configure document types (ID, diploma, contract, social security, photo, license, etc.) and upload media per employee with list and delete actions. Seed defaults in one click.

  • Rewards, warnings, and complaints

Review now

Features

  • Rich product catalog

  • Attributes and value lists

    Add structured attributes—material, weight, warranty, origin, etc.—with fixed value lists for data quality. The same structure supports filters, exports, and integrations.

Review now

Features

  • Rental accounts (customer + location)

    One account per customer/location pair within a workspace. Additional rent-outs append to the open account or create it if missing—similar to a running account without a separate contract entity.

  • Segment-based earned revenue

    Each line earns from its start date; partial returns create segments (e.g., 10 units 5 days, then 7 units 5 days). Balance due equals earned revenue minus payments; overpayments are highlighted.

  • Rent out and return

    Modal workflow: Rent Out (customer/location or account, date, line items with qty, unit price, period) and Return (pick account, active lines, partial or full quantities, return date). Full return closes the line.

  • Payments and timeline

    Record payments per account with amount, date, method (cash, wire, EFT, check), reference, and notes. Timeline lists rent-outs, returns, and payments chronologically.

Frequently Asked Questions

Find answers to common questions about our platform and services.

Yelken360 is a multi-module ERP and business management platform that brings together your workflows from proposals to invoicing, stock management to reporting. It is designed for small and medium-sized businesses, sales teams, manufacturers and service providers. Thanks to its workspace-based structure, you can manage multiple companies or brands from a single account.
A workspace is an isolated environment for your company, a brand or a separate project. Each workspace has its own products, proposals, customers and subscription plan. This lets you manage multiple business units with a single login. You can create new workspaces from the admin panel and assign team members and permissions per workspace.
Each workspace is linked to a subscription plan (e.g. Starter, Pro). The plan defines which modules (Product, Proposal, Stock, Invoice, etc.) are enabled and the usage limits (e.g. maximum number of products, proposals). When you reach a limit, the system notifies you; you can increase limits by upgrading your plan or requesting a custom plan.
With the proposal module you can create professional proposals from templates or from scratch, add product or service line items, and have discounts and taxes calculated automatically. You can download proposals as PDFs or send them by email. Approved proposals can be converted to orders, so the flow from proposal to invoice stays in one place.
In the product module you can create product records, define categories and brands, and optionally add variants (size, colour, etc.). The stock module handles in/out movements and warehouse or location-based stock tracking. You can keep stock levels under control with stock reports and low-stock alerts.
With the invoice module you can create invoices from proposals or orders, edit invoice lines and generate PDFs. Invoices are calculated according to the workspace currency and tax settings. For payment tracking, invoice statuses (pending, partially paid, paid) are used; a dedicated payments module may be available as an add-on depending on your plan.
