Nominasol is the payroll and labour management software by TeamSystem/DELSOL, designed for labour advisory firms and HR departments in SMEs. As an Official TeamSystem Partner, at Summum Sistemas we implement the tool, migrate your historical data and resolve day-to-day incidents so that personnel management never becomes a bottleneck.
Nominasol covers the full labour management cycle: payroll preparation under any collective bargaining agreement, social security settlement via NS Conect@ and SILTRA, contract management, income tax (IRPF) withholding calculation, sick notes and leaves of absence, and generation of the official files required by the Social Security Treasury. The software runs exclusively on Windows and is developed by Software del Sol (DELSOL), a company headquartered in Mengíbar (Jaén) that joined the Italian group TeamSystem in February 2021.
For a labour advisory firm handling dozens of client companies, Nominasol offers the ability to operate multiple entities from a single environment, automatically apply updated collective agreements, and generate social security remittance files in the format required for each procedure. The initial learning curve and the periodic updates imposed by changes in contribution rates, contract types or official forms are precisely where the external support of a specialist consultant makes the difference.
At Summum Sistemas we have been accompanying SMEs and advisory firms in the implementation and maintenance of management solutions since 2007. When a company already uses Nominasol but has gone months without updating collective agreements, has accumulated unsettled payroll runs, or needs to integrate payroll data with Contasol for automatic accounting entries, our team steps in to bring the system up to date and keep workflows running reliably. If your firm is implementing Nominasol for the first time, we define the company structure, contribution groups and collective agreements with you from day one.
We analyse how you currently manage payroll: software in use, headcount, applicable collective agreements and level of integration with accounting. With that map we define the scope of the implementation or migration and the go-live schedule.
We install Nominasol in your working environment (local workstations or the advisory firm's server), configure the companies, contribution groups, current income tax tables and applicable collective agreements. If you are migrating from another software, we transfer the historical employee and payroll data.
We train the responsible team on the main workflows: employee registration, monthly payroll calculation, social security generation via NS Conect@/SILTRA, contract processing and file submission to the Treasury. The go-live runs in parallel with your real process to validate every result.
We resolve incidents by phone, email and remote access. We update collective agreements and tables when regulatory changes occur and proactively notify you of developments that affect your client portfolio or your own workforce.
The operational detail: what we deliver as part of the work and what we keep alive afterwards.
Greenfield implementation
Company registration, agreement configuration, contribution groups, income tax tables and work-centre structure tailored to your situation.
Migration from another software
Transfer of historical employee, contract and payroll data from other programmes (a3nom, Sage, ContaPlus Laboral or others), with reconciliation verification before the first live payroll run.
NS Conect@ / SILTRA connection
Configuration and testing of the connection to the Social Security systems for the monthly settlement of contributions, registrations, deregistrations and employee data changes.
Integration with Contasol
Configuration of the automatic accounting entry from Nominasol to Contasol to eliminate double data entry and reduce errors at the monthly close.
Collective agreement and regulatory updates
We keep collective agreement tables, contribution rates and official forms up to date every time a change affects your sector or your clients.
Technical and functional support
Assistance with programme incidents, resolution of errors in file generation for the TGSS, and guidance on the correct use of each software function.
Payroll management does not live in isolation: we connect it with Contasol accounting, with the cloud-integrated DELSOL 360 suite, and — when the advisory firm needs to automate document validation workflows — with the AI agents from Summum IA.
Contasol automatically receives the payroll accounting entry generated by Nominasol; we implement both in parallel to eliminate double data entry in the advisory firm.
View service → sistemasDELSOL 360 is the cloud suite that integrates Factusol, Contasol and Nominasol in a single environment accessible from any device; ideal for advisory firms that want to leave the Windows desktop behind.
View service → iaSummum IA offers copilot solutions for professional firms that automate the classification of labour documents and the review of payslips before client sign-off.
View service →Nominasol includes a database of collective agreements that is updated with each new software version. For company-level agreements or very specific sector arrangements, the manual configuration of salary tables is straightforward; we assist with that initial setup so that payroll calculations are always correct.
Yes. Nominasol allows you to create and manage multiple companies from the same programme, making it particularly well-suited for labour advisory firms that work with a portfolio of business clients. Each company has its own agreement configuration, contribution groups and income tax parameters.
Nominasol generates files in the format required by the Social Security Direct Settlement System (NS Conect@) and by SILTRA for the submission of TC2 returns and affiliation records. During implementation we configure and test that connection to ensure submissions are made correctly from the very first month.
Yes. The migration process involves exporting data from the current software (employees, contracts, historical payroll records) and adapting it to Nominasol's import format. At Summum Sistemas we carry out that migration with a reconciliation check between source and destination before the transfer is considered complete.
Nominasol is a desktop programme for Windows. If you need access from multiple devices or from outside the office, the alternative within the TeamSystem/DELSOL ecosystem is the DELSOL 360 suite, which integrates Nominasol's functions in a cloud environment. At Summum Sistemas we help you evaluate which option best fits your workflow.
